Abstract: A phase-shift optical mask for exposing a pattern
on a wafer via an exposure lens is formed on a
transparent substrate 41. On the substrate there is a
light-transmitting region 42 having a width
m(L + 0.2λ/NA), where m denotes the reducing projection
magnification, L denotes the width of the opening
actually developed on the wafer, λ denotes the
wavelength of the exposure light and NA denotes the
numerical aperture of the exposing lens. A feature in
the mask is made up of a first transparent phase-shift
region 43 around the periphery of the light-transmitting
region 42, having a width
(mλ/2NA)[1.1 - (NA/λ)(L + 0.2λ/NA)], a first light-blocking
region 44 having a width 0.1mλ/NA around the
outside of the first phase-shift region, a second
phase-shift region 45 on both outer sides of the first
light-blocking region, of a width 0.1mλ/NA, and a
second light-blocking region 46 provided on both outer
sides of the second phase-shift region. This
construction is capable of rendering very fine
features. A process for making it is also described.

Abstract: A method and apparatus for sorting books of sheets in which individual books
are generated in succession is provided. This process entails the stacking of cut sheets
that form a completed book in an offset arrangement relative to adjacent books. Each
offset stacked book is removed from the other books by applying a lifting force
between the lowest book in the stack and the next book in the stack while the lowest
book in the stack is allowed to bend away from the next highest book in the stack.
The bend forms a space, tunnel or separator entrance opportunity into which a
projection or other separator structure is directed. The lowest book is lowered onto a
conveyor and moved away from the stack. The process continues for each successive
next-highest book in the stack. A support mechanism is provided to maintain the
lowest book at a selected elevation as the projection moves inwardly. The support
moves away concurrently to deposit the lowest book on the conveyor. A pair of
alternating movable belts can be used for both the projection and the support on
alternating sides of the stack.

Abstract: L'invention concerne un billet de lignes aériennes sans indication d'heure qui permet à un passager d'acheter une place dans un avion pour un itinéraire choisi (par exemple, de New York à Los Angeles le 3 mars), le vol étant sélectionné ultérieurement par les compagnies aériennes. Elle concerne également divers procédés et systèmes pour rattacher un billet sans indication d'heure à un vol donné. Un procédé cité en exemple consiste à: (1) mettre à la disposition du passager un billet sans indication d'heure; (2) examiner plusieurs vols qui remplissent les conditions dudit billet sans indication d'heure pour déterminer quel vol choisir et; (3) avant le départ, informer le passager sur le vol choisi. Les modes de réalisation de cette invention permettent aux passagers de bénéficier de tarifs aériens réduits en contrepartie d'une heure de départ flexible; à leur tour, les compagnies aériennes ont la possibilité de remplir les places qui, en d'autres circonstances, n'auraient pas été réservées. Etant donné la flexibilité demandée aux passagers détenteurs d'un billet sans indication d'heure, les billets sans indication d'heure de départ sont de nature, d'une part, à attirer les voyageurs d'agrément qui ne désirent pas acheter leur billet aux tarifs publiés et, d'autre part, à 'tenir à l'écart' les voyageurs d'affaires non désireux de courir le risque de perdre une journée entière au départ ou à l'arrivée. En outre, la flexibilité demandée aux passagers détenteurs d'un billet sans indication d'heure ne se limite pas nécessairement à l'heure de départ: elle pourrait aussi concerner la compagnie aérienne, l'aéroport de départ, l'aéroport de destination ou prendre la forme de toute autre restriction qui augmente la marge de manoeuvre de la compagnie aérienne en matière de choix du vol pour un passager donné. Selon les modes de réalisation de cette invention, les compagnies aériennes ont la possibilité de remplir les places qui, en d'autres circonstances, resteraient vacantes et de stimuler la demande latente et non satisfaite en matière de voyages d'agrément, sans avoir à modifier leur structures tarifaires sous-jacentes.

Abstract: Disclosed is a method and apparatus for testing a semiconductor memory
having a plurality of memory cells arranged in rows and columns and a plurality of
sense amplifiers, each for amplifying memory cell signals of a common row or column.
In an illustrative embodiment of the method, a voltage level or test pattern is written
into at least one target cell of the memory cells. A word line coupled to the target cell
is then activated and subsequently deactivated, to thereby modify the voltage level
stored in the cell, while the associated sense amplifier is prevented from refreshing the
cell as the word line is activated, e.g., by disabling the sense amplifier. A test bit line
voltage is then applied to a bit line coupled to the cell to charge the same. Data is then
read from the target cell with settings of the associated sense amplifier enabled, and
compared to the original voltage level written into the cell. The process is repeated for
different test bit line voltages. The method can be used to determine the signals at the
sense amplifiers during normal operation of the memory, without employing complex
and costly picoprobes.

Abstract: A first final target input rotation speed is calculated according to a
throttle opening and a vehicle speed, and a second final target input rotation
speed is calculated by applying an upper limit to the first final target rotation
speed. The upper limit is determined so as to reduce noise outside the vehicle.
A second final target speed ratio is set from the vehicle speed and second final
target input rotation speed, and a time constant of a speed ratio variation is
determined from the vehicle speed and first final target input rotation speed.
By transiently controlling the speed ratio variation using the second final
target speed ratio and time constant thus obtained, an excessive increase of
engine rotation speed is prevented while retaining a desirable feeling of
acceleration when there is a kickdown operation of the vehicle.

Abstract: A method of statically and dynamically controlling the height and
angle of a feed tray (210) in an electrophotographic printing machine. The paper
supply starts with the tray (210) lead edge ramped up 1.4 degrees and paper is
loaded. Required paper properties are inputted or sensed automatically (e.g.,
gsm, size, etc.). The elevator raises to lowest possible stack height (to
maintain stack control using tray guides in preparation for air system turning
on). The initial tray angle is removed based on paper gsm and the air system
activates fluffer and air knife jets (360), but vacuum is valved to off position. The
stack height arm (352) is raised & lead edge attitude sensor (340) is interrogated for top
sheet position relative to feed head acquisition surface (sensor may be position
sensitive device type or multiple sensors with different focal lengths, etc.).
Based on positions sensed by stack height and lead edge attitude sensors, the
tray angle and/or stack height is adjusted until the desired sensor states are
achieved. Upon completion of adjustments to the tray angle, stack height is
verified. Feeding commences and stack height and lead edge attitude positions
are checked each feed with corrections made accordingly.

Abstract: A technique of monitoring the cache footprint of relevant threads
on a given processor and its associated cache, thus enabling operating
systems to perform better cache sensitive scheduling. A function of the
footprint of a thread in a cache can be used as an indication of the
affinity of that thread to that cache's processor. For instance, the
larger the number of cachelines already existing in a cache, the smaller
the number of cache misses the thread will experience when scheduled on
that processor, and hence the greater the affinity of the thread to that
processor. Besides a thread's priority and other system defined
parameters, scheduling algorithms can take cache affinity into account
when assigning execution of threads to particular processors. An
apparatus is described that accurately measures the cache footprint of a
thread on a given processor and its associated cache by keeping a state
and ownership count of cachelines based on ownership registration and a
cache usage as determined by a cache monitoring unit.
